PROMETHEUS MS120 Non-Linear AEG Spring | Precision Power & Durability

Elevate your Airsoft AEG´s performance to the highest standard with the PROMETHEUS MS120 Non-Linear Spring. Engineered in Japan for the discerning player and technician, this spring is the definitive upgrade for those who demand unparalleled consistency, enhanced gearbox longevity, and a significant boost in power. Move beyond standard linear springs and experience the tactical advantage of advanced non-linear compression technology.

The MS120 is meticulously designed to transform your AEG´s firing cycle. Its core innovation lies in its irregular pitch coiling, which provides a variable compression rate. This means the initial force required to pull back the piston is significantly lower, drastically reducing the initial shock and strain on your piston´s pickup tooth and gear set. As the spring compresses further, its power ramps up smoothly and rapidly, culminating in a forceful and decisive release. This intelligent design not only ensures a smoother, quieter gearbox operation but also actively works to extend the life of your critical internal components.

Key Benefits:

* Enhanced Gearbox Longevity: The non-linear design minimizes the violent initial impact on the piston and gears during pickup, reducing wear and tear and lowering the risk of premature failure, especially in high-speed or high-stress builds.
* Superior Shot-to-Shot Consistency: By delivering a more controlled and stable release of energy, the MS120 provides a remarkably consistent muzzle velocity. This stability is crucial for tightening your BB groupings and achieving predictable accuracy at extended ranges.
* Optimized Power Output: Rated for approximately 120 m/s, this spring provides a substantial increase in velocity, making it an ideal choice for outdoor fields and MILSIM events where range and power are paramount. Achieve the performance you need to dominate the field.
* Smoother Firing Cycle: Players will notice a smoother, less jarring firing cycle. This can contribute to a more stable shooting platform and potentially improve the rate of fire by allowing the motor to cycle the gearbox with less initial resistance.

Main Features:

* Advanced Non-Linear (Irregular Pitch) Design: The cornerstone of its superior performance, offering variable tension throughout the compression cycle.
* Precision Ground Ends: Both ends of the spring are perfectly flat, ensuring optimal seating against the spring guide and piston head for flawless alignment and energy transfer.
* Exceptional Durability: Built to withstand countless cycles without fatiguing or losing power, ensuring your AEG performs at its peak for longer.
* Made in Japan: A testament to the highest standards of quality control, precision engineering, and performance that the Prometheus brand is renowned for.
